Wow those are some sweet pick ups. I also have to ask what bulbs you are running, because that looked a little dif in Marvins tank. Man they have some pop to them, saweet.
Alright, well you all are going to HATE this answer... But I have no idea what bulbs they are... I bought a used fixture for the tank they are in, all I know is they are 150 watt DE bulbs... The guy I got the fixture from said they were 10k bulbs, and there is also 2 96 watt PC actinics on it... I was thinking of getting some 14K phoenixes, but I don't know...
As for the colors, must be the actinic supplementation?? Also, I play around with the white balance on my camera... No photoshopping or anything though.
